pension plan reform Aymo Brunetti fuw

https://www.fuw.ch/article/die-jungen-sind-die-verlierer/
when science and politics clash ...Dieser Gedanke muss unbedingt in die nächste Reform eingebracht werden. Man muss in die Richtung der versicherungsmathematischen Wahrheit gehen. Das müssen wir vorab den Jungen erklä­ren. Sie sind, ohne dass es allen bewusst wäre, die grossenVerlierer dieser Reform....Gemäss einer Studie zur Schweizer Generationenbilanz öffnet sich heute eine langfristige Finanzierungslücke von über 170% des Bruttoinlandprodukts. Sie reduziert sich mit derVorlage ein wenig, vor allem aufgrund der Mehrwertsteuererhö­ hung. Aber es bleibt eine enorme Lücke
von 135% des Bruttoinlandprodukts.....In den kommenden zehn Jahren werden in der
Schweizrundeine MillionMenschenpensioniert, das ist ein Fünftel aller Arbeitskräfte. Zusätzlich verknappend wirkt die Umsetzung der Masseneinwanderungsinitiative. Die Unternehmen werden sich schon bald um die älteren Arbeitskräfte streiten.....Jemand, der zwischen 25 und 45 Jahre alt
ist und für die Altersvorsorge 2020 stimmt, ist entweder ein ungewöhnlicher Altruist oder hat die Auswirkungen der Vorlage nicht verstanden. Das sind die Jahrgänge, die die Reform bezahlen

That is by design. The school is modelled on the Kolmogorov Physics and Mathematics School in Moscow, which from the mid-1960s took Russia’s smartest 15-year-olds and exposed them to the best maths teaching in the country. Michael
Gove, Britain’s education secretary from
2010 to 2014, imported the idea, pushing
universities to start specialist maths colleges. The aim was to make it possible for
any child to have an “Eton-level education” in maths or physics, recalls Dominic
Cummings, a former adviser to Mr Gove

By lifting obstacles to job
changes and giving workers a social safety net that enables them
to refuse the crummiest jobs, societies can foster employment
that is not just full, but fulfilling.

Physics

Andrew Geraci’s equipment, on the other
hand, comprises a glass bead 300 billionths ofa metre across, held in a lattice of
laser light inside an airless chamber. The
power it consumes would run a few oldfashioned light bulbs. Like researchers at
the LHC, Dr Geraci and his team at the University of Nevada, in Reno, hope to find
things unexplained by established theories such as the Standard Model of particle
physics and Newton’s law of gravity.
Whereas the LHC cost around SFr4.6bn
($5bn) to build, however, DrGeraci’sset-up

In Dr Geraci’s experiment the suspended bead scatters laser light onto a detector.
If a force displaces the bead, the pattern of
light changes, permitting the bead’s new
position to be calculated. In work published last year in Physical Review A, his
team showed that the apparatus can detect
forces of a few billionths of a trillionth of a
newton. (Anewton isaboutthe force exerted by Earth’s gravity on an apple.) Their
next step will be to move a weight past the
bead at a distance of five microns (five
thousandths of a millimetre), to measure
the gravitational attraction between them.
That experiment is now under way

Any
departure from this law would provide
support for theories which hope to solve
what is known as the hierarchy problem of
physics. This is the question ofwhy gravity

namely electromagnetism and the weak

tween gravity and these forces explains,

for example, why a small magnet can pick
up a paper clip against the gravitational
force ofan entire planet.

always hard in the social sciences.

Mr Trump is hardly the first tycoon to discover that business
and politics work by different rules. If you fall out over a property deal, you can always find another sucker. In politics you
cannot walk away so easily. Even if Mr Trump now despises
the Republican factions that dared defy him over health care,
Congress is the only place he can go to pass legislation.

Zwicki

How is it that a man with so meager an understanding of the Jaws of physics could have been so prescient? My own opinion is that he embodied a remarkable combination of charat.-ter traits: enough understanding of theoretical physics to get things right qualitatively, if not quantitatively; so intense a curiosity as to keep up with everything happening in all of physics and astronomy; an ability to discern, intuitively, in a way that few others could, connections between disparate phenomena; and, of not least importance, such great faith in his own inside track to truth that he had no fear whatsoever of making a fool of himself by his speculations. He knew he was right (though he often was not), and no mountain of evidence could convince him to the contrary

Einstein pedagogics

Einstein began his search for a new law of gra~ity in 1907. His initial steps were triggered and guided by a writing project: Although the patent office now classified him as only a "technical expert second class" (recently promoted from third class), he was sufficiently respected by the world's great physici!its to be ir1vited to w1·ite a review article for the annual publication Jahrbuch der Radioaktivitiit und Elektrom1r. about his special relativistic laws of physics and their consequences. As he worked on his review, Einstein discovered a valuable strategy for scientific research: The necessity to lay out a S\tbject in a self-contained, coherent, pedagogical manner forces one to think about it in new ways. One is driven tc> examine all the subject's gaps and flaws, and seek cures for them.

Minkowski teacher to einsteins stud2nt : lazy dog

Russian by birth, had left the ETH in Zurich to take up a more attractive professorship in Gottingen, Germany. (Science was as international then as it is now.) In Gottingen, Minkowski studied Einstein's article on special relativity, and was impressed. That study led him to his 1908 discovery of the absolute nature of four-dimensional spacetime. When Einstein learned of Minkowski's di~;cove:ry, he was not impressed. Minkowski was merely rewriting the laws of special relativity in a new, more mathematical language; and, to Einstein, the mathematics obscured the physical ideas that underlie the laws. As Minkowski continued to extol the beauties of his spacetime viewpoint, Einstein began to make jokes about Gottingen mathematicians describing relativity in such complicated language that physicists wouldn't be able to understand it. The joke, in

Poincarre picasso einstein

http://www.theguardian.com/science/blog/2012/jul/17/henri-poincare-einstein-picasso

Picasso was particularly struck by Poincaré's advice on how to view the fourth dimension, which artists considered another spatial dimension. If you could transport yourself into it, you would see every perspective of a scene at once. But how to project these perspectives on to canvas? Poincaré's suggestion in Science and Hypothesis was to do so one at a time, showing each in succession. Picasso disagreed. He wanted to depict them all at once.

Time machine

Your starship's rocket engines will blast all the way with a 1-g acceleration, so that you and your crew can experience a comfortable 1-Earth-gravity force inside the starship. The ship will accelerate toward the galactic center for half the journey, then it will rotate 180 degrees and decelerate at t g for the second half. The entire trip of 30,100 light-years distance will require 30,102 years as meas1ued on Earth; but as measured on the starship it will require only 20 years. In accordance with Einstein's laws of special relativity,118 your ship's high 8peed will cause time, as measured on the ship, to "dilate"; and this time dilation (or lime warp), in effect, will make the starship behave like a time machine, projecting you far into the Earth's future while you age only a modest amount.!Z7 You

Warped time einstein, only 25 billions years ago vs 6 billion ppl living in the planet

The primary event occurred at some time between ten and twenty billion years ago. Perhaps the most dramatic support for the hypothesis was the discovery of the degraded remnants of the light waves that accompanied a late phase of the initial explosion.
